p ya claims.

My invention `relates :to .'fruiti Ajuice lextractorsv and morefparticularly to a deviceior removing juice Y from oranges, lemons, grapev fruit, and fthe like. ,i

. In the'operation'of extracting juice from citrus fruit, there are ve factors to be considered, namely, theljuice itself, rthe pu1p,-the bre, the seeds, and the rind.' In thoseajuicerextractors YWhichperform the juicing-operationi-by crushing or pressing the halves of oranges or thelilre, f some of theoil lcontained-.inthe rind is expressed Y and mingles with the juice'.Y This imparts to the juice a slightly bitter taste which is not palatable to some people. Furthermore, it appears that the oil in the rind has a deleterious effect upon keeping qualities of the Vjuice in a refrigerator.

' Then, too, the juice which is extractedin a juicer i a juice extractor in lwhich the juice is reamed Another object of my, invention is to provide a simple device which is easily cleaned and which will express juice from citrus fruit in al simple and convenient inanner.

In general, my invention contemplatesthe pro' vision of a 'bowl provided with a juice draining outlet. 'Ihe bowl is mounted upon any suitable standard so thata juice receiving receptacle may of the reamer element be positioned beneath the outlet. Positioned Within the bowl is a. reamer which may be made of glazed ceramicv material. Vvided with rounded edges in the form ofjllets, which will serveto Wipe the pulp against the rind rather than cut or squeeze the pulp from` the rind. The reamer is formedr Vintegral with a strainer plate. The combined reamer and vstrainer plate is removably mounted in the bowl. Pvotallywmounted adjacent the bowl is an arm containing a bearing'for Va shaft, adapted to be' rotated by a suitable handle and carrying an inverted bowl provided with impaling members. Pressure exerting means are provided so that the shaft which is mounted for movement along its axis may be pressed downward from'over the reamer and simultaneously rotated.

More particularly referring now to the drawing, upon any suitable standard which may be formed of a base member I, provided with legs 2, IV sup` port a bowl 3 provided'with a funnel shaped bot- Y tom t, terminating in an outlet 5 under which The reamer is pro.-

any suitable juice receiving receptacle is adapted Y base member provided with openings 3 of such Y size that theyare radapted to prevent the passage of seed, thus'enabling them to act as strainingV openings for the juice. Recesses22 are provided in the base of member 'i for intertting with lugs t. Integral with the base member are a plurality of upstanding members 9 formed with tapered sides lil, terminating in a fillet l l. The llet presents a rounded edge adapted to wipe the juice cells against the rind and express the juice therefrom, while permitting the pulp or membranelike material which forms the casing for the juice cells, to be retained against the rind, when the Yfruit is rotated by the rotating means, hereinafter more fully described. The strainer and' reamer may be made of glazed, ceramic material and ner is an inverted cuplike member,V I1 provided with a plurality of rind impaling members |8.

Loosely mounted upon, shaft I6 is a pressure-l exerting member IS, adapted to bear against shoulder 2U, formed upon the inverted cap l1. The shaft i6 is adapted to be rotated by a suitable handle 2l.

In operation, the arm Hl is swung to the dotted line position shown in Figure l, carrying with it the inverted cup and associated operating parts. One half of the citrus fruit to be subjected to a juice extracting operation is placed, with the cut side downwardly, over the reamer. The arm is then swung, permitting the inverted cup to engage the outside of the fruit. Pressure is exerted by means of member i3 upon the inverted cuplike member, movingit downwardly in bearing i5 and impaling the rind at a plurality of points with spikes i8. Exerting a slight pressure with one hand upon member i9, the operating handle 2i is rotated with the other hand.v The speed with which the juice may be expressed is governed by the speed of rotation and by the pressure exerted. The rounded fillets ll wipe by the inside of the fruit and local pressure is exerted by the reaming members against the pulp and rind which is, in turn, supported by the inverted cup member l?. The juice is rapidly and cleanly expressed. It is free from rind oil, seeds, and pulp.

It will be observed that I have accomplished the objects of my invention. I have provided a simple device which may be easily broken down for cleaning, which will express the juice free of seeds, pulp and rind oil.

It Will be understood that certain features and subcombinations are of utility and may be emvployed without reference to other features and not to be limited to the specic details shown and described. Y j

Having Ythus described my invention, what I claim is:

1. In a fruit juice extractor, a fruit juice receiving member, a standard for supporting said member, a fruit juice outlet for said member, a juice extracting reamer, lugs in said juice receiving member 4for positioning said reamer therein, an arm positioned adjacent said juice receiving member, said arm carrying a bearing and adapted to be swung into position over saidreamer, a shaft slidable in said bearing, a fruit receiving member secured to one end of said shaft for rotation therewith, an operating handle secured to the opposite end of said shaft and a bearing member loosely positioned upon said shaft, adapted to transmit manual pressure upon said fruit receiving member. Y

2. A fruit juice extractor as in claim 1 wherein said reamer is provided with a strainer.
